The bilingual people were able to respond faster to the shifting prompts.
会说两种语言的人会对提示的变化反应更快。
Researchers then gathered 80 more people for a second experiment: 20 young bilinguals, 20 young monolinguals, 20 old bilinguals, and 20 old monolinguals. This time, researchers used fMRI scans to monitor brain activity during the same shape- and color-identifying tasks. Gold and his team found that bilingual people were not only able to switch tasks faster — they had different brain activity than their monolingual peers.
研究者接着召集了80个人参与第二项实验:20个说两种语言的年轻人,20个说一种语言的年轻人,20个说两种语言的老年人,以及20个说一种语言的老年人。这次,研究者用功能磁共振成像扫描法检测参与者们参加同样的实验时大脑活动的情况。古尔德和他的团队发现,说两种语言的人不仅转换任务的速度更快,而且他们大脑的活跃程度也同说一种语言的同龄人不同。
“It allows a sort of window into how the brains of people who have different cognitive processing abilities are processing the same stimuli in different ways,” said Kristina Visscher, a neurobologist at the University of Alabama School of Medicine who did not work on the study.
“这个研究让我们看到,拥有不同认知处理能力的人,大脑是如何用不同方式处理同一个刺激物的。”克里斯蒂娜·维斯切如是说,她是阿拉巴马大学医学院一位神经学家,并没有参与此次的研究。
